Difference between Type&Cross and Type&Screen

  1. Hi everybody,

    I know this may sound like an easy question, but I can't figure out the difference between the two. They never really went into it in nursing school. I asked my preceptor, but her reply didn't make much sense to me, so I have no clue! Can anyone fill me in?? TIA!

    Type and screen determines Blood type, Rh, and any antibioties present in CASE you need blood. No blood is actually prepared to transfusion.

    Type and cross determines the same information, but goes one step further and gets blood ready to be transfused based on that information.

    To the best of my knowledge, a type and cross means they type the blood and cross match it for PRBC units. A type and screen means they type the blood and screen for anitbodies that may cause reaction to transfused blood. When they do a screen also they have to match the available blood units antibodies to antibodies of the patient also. The cross just means they have the correct blood type available to infuse.
    I know i have had to wait up to a couple hours to recieve blood from a neighboring towns blood bank because the patient had certain antibodies that made giving her a unit of what we had available impossible.

    At my hospital they are quite specific about the T&S vs TCM. The T&S means the blood is checked but a specific number of units of blood is not designated for that pt. The antibodies are checked etc but PRBC's are not set aside for that pt. We are supposed to use this if a transfusion is possible but not necessarily going to happen. According to lab it would take about another 15 mins to have blood in hand if ordered. A T&CM designates a certain number of units of PRBC's for that pt. They are labeled and set aside. This is used if giving blood is a definite or the additional 15 min wait is to long. If an emergency arises the PRBC's from a T&CM that is designated for pt X can not be used for pt Y. With a T&S all the preliminary work is done but specific units are not assigned and available for anyone to use. Working at a major transplant/truma center we see this alot. The lab prefers for us to utilize the T&S whenever possible.
